- INSPEC is a program to look into sectors of floppy or hard disks,
- and into files, especially if they contain numbers instead of
- ASCII text. It can also be used to show FAT 1 and 2 of any standard
- device. INSPEC accesses all data via GEMDOS or BIOS calls.
- It is NOT a disk monitor, it allows only listing (also on a protocol
- file), but no changing of the data in a file or at an absolute position
- of a disk.
-
- INSPEC is key-driven. The meaningful keys are always displayed, and a
- short explanation is given, when the ? key is pressed.
- The I key ("interpret") allows interpreting directory sectors, floppy
- & harddisk boot sectors, and changing display format (integers, MS-DOS-
- integers...) in a separate menu. The Q key ("quit") returns to
- the main menu and from there to the shell (desktop).
-
- Useage:
- 1) activate the program INSPEC.TOS (from desktop or other shell)
- 2) when prompted, give a protocol file name (may be PRT: for
- immediate printing), or press RETURN to get output on display
- screen
- 3) when prompted for a file name, enter the name of the file to be
- inspected. If you don't want to see a file, but rather some
- sectors of a device, simply press RETURN without entering a name.
- You will the be prompted for a device letter (small or capital,
- a = 0 = floppy A:, c = 2 = RAMdisk or harddisk C: etc.)
-
- Press any valid keys, e.g. N to see the next part or sector, or S to
- select the starting point for display. Change to other file (F) /
- drive (A) / FAT listing (T) / directory listing (D). The S key selects
- the sector number in A (drive) mode, the byte offset in F (file)
- mode, and the first allocation unit in T (FAT) mode.
-
- The display format is chosen to fit one sector on one screen.
- The characters in dump format (hex plus some characters shown,
- others represented by a period) are chosen to be printable on most
- available printers; if you want to see all characters, use character
- format (I C).
-
- Within directory listings (D) or directory sector interpretation (I D),
- the flags mean
- S = system file
- H = hidden file
- D = subdirectory
- V = volume label
- C = written & closed flag (not properly used by GEMDOS)
- R = read-only file
- also file size and creation date (European format) are given.
- In a directory sector, in addition the first AU number and the
- (unused) flag array is listed.
-
- FAT listings (T) of both 12 and 16 bit FATs are possible. An FAT
- entry is a pointer to the next AU of a file. -1 means EOF, 0 is an
- empty AU. Other negative numbers signal bad sectors.
- N.B. AU 0 and 1 are reserved, the first data sector is in AU 2.
-
- Finally, you may copy the program and use it, but I take no liability
- for any result, and you must not make profit from it without my
- written consent.
